Mixing is one of the critical processes in industry,which usually counts for a considerable portion in the industrial cost today [1].However,thorough and cost-effective mixing processes are to some extent still absent from the research reported in the existing literature [2].It has been argued and demonstrated that chaotic vibration can provide the best possible thorough and efficient mixing of fluids.This work reports a practical approach to applying chaotic perturbations into a liquid mixing process so as to achieve better mixing quality.The design is to use sampled output signals from a chaotic circuit,where the mixing process uses a most widely utilized mixing device,the stirred tank.Laboratory experiments are carried out with careful comparisons,showing the superiority of chaos over other conventional liquid mixing methods.
